EDWARD W, N. BOOSEY, OF DETROIT, MICHIGAN FLOOR-DRAIN.

Specification of Letters Patent.

Patented Nov. 5-, 1918.

Application filed February 2, 1917, Serial No. 146,079. Renewed July 15, 1918. Serial No. 245,071.

To all whom it may concern:

Be it known that I, EDWARD W. N. Boosnr, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Floor-Drains, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference bein had to the accompanyin drawings, whic form a part of this speci cation.

This invention relates to floor drains, and its object is a valve controlled floor drain adapted to prevent the water from backing up from a connected sewer and so constructed as to enable the valve and supporting parts to be readily removed for the purpose of cleaning. A further object is a floor drain in which the clean-out passage terminates at the floor level outside the area of the usual perforate cover. Another object of the invention is a floor drain having a bowl and a central cylindrical chamber having a valve controlled inlet, the said chamber being removablyconnected with the bowl. These and other objects and the several novel features of the invention in its preferred form are hereinafter more fully threaded to receive a threaded end of a sub-.

stantially cylindrical chamber 3 provided with a screw threaded cap 4 which closes the upper end thereof. The lower end of the chamber is open and of a diameter substantially equal to the internal diameter of the'trap. A perforate cover 5 is provided for the bowl which is flanged to receive the same, and this cover is of shallow cu shaped form and should be placed substantially on a level with the floor line 6, in order that material may flow readily into the bowl through the erforate cover. The cover is preferably eld in position by a' screw 7 extending into the cover member 4 of the cylindrical portion 3.

The cylindrical portion 3 has a threaded aperture 8 on one side thereof into which is threaded a tubular member 9 carrying a valve 10 pivotally mounted thereon by means of a bracket 11 of ordinary form. The valve is loosely mounted in the bracket to enable it to readily set on the end of the tube 9. The valve opens inwardly into the tubular member 3 and thus allows material to flow from the bowl into the sewer through the trap 2 but a back flow of fluid through the trap closes the valve 10 and the cylindrical member being otherwise closed, back flow into the bowl is entirely prevented.

With the usual floor drain a plugged opening is provided between the trap andbowl,

the plug being within the bowl in such cases and with the cover 5 in place the traps are oftentimes left with the plug removed thus establishing afree opening between the trap and the floor drain through which gases from the sewer may escape into the building. In this present invention the device is provided with a conduit 12 formed at the side of the bowl and terminating at the floor level which conduit is closed by the usual plug 13. By reason of this plug being positioned at the floor level it may at all times be readily seen if the conduit is closed to the sewer without necessity of removing the cover of the bowl or otherwise disassembling the parts.

By provision of the cover 4 to the central chamber 3 the valve is readily accessible should it become clogged in any manner and the assembled valve and tube 9 is readily placed in position in the interior of the chamber through the opening closed by the cover member 4. Furthermore, by reason of the discharge chamber 3 beingseparabl connected with the bowl, the said mem er 3, valve, supporting parts, etc, may be assembled, and as a unit secured in position in the bowl and by making the bowl and chamber 3 separable the process of casting is much simplified.

Having thus briefly described my invention, its utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States is '1. In a floor drain, a bowl, a trap formed integrally therewith and opening into the bowl centrally of the bottom, a cleanout conduit formed integrally with the trap and bowl leading into the trap portion and terminating on a level with toe top of the bowl connected exteriorly therewith, a tubular member extending vertically into the bowl having an opening thereinto and discharging through the outlet, and a swing valve adapted to close the inlet opening by back flow of fluid from the trap.

In a floor drain, a bowl, a trap formed integrally therewith and opening thereinto at the center of the bowl bottom. the trap having an enlarged threaded portion adjacent the connection with the bowl, a cylindrical chamber adapted to be threaded into the said enlargement and extending upwardly into the bowl, said chamber having an inlet adapted to allow fluid to flow freely from the bowl into the chamber, said chamber being otherwise closed, a swing valve controlling said opening, and a perforate cover for the bowl.

3. In a floor drain, a bowl, a trap formed integrally therewith and opening into the bowl substantially centrally of thebottom, a discharge chamber positioned centrally within the bowl and connected with the said opening, the discharge chamber having an Laeaeea inlet opening into the bowl, a swing Valve adapted to close the inlet by back flow into the chamber, the said chamber having a removable cover at the upper end, and a perforate cover for the bowl centrally secured to the chamber cover, the bowl cover being of shallow cup shapec. form.

at. In a floor drain, a bowl having an outlet, a trap connected therewith, a chamber secured within the bowl having an opening into the bowl and discharging through the said outlet, the chamber being otherwise closed to the bowl, and a swing valve adapted to close the inlet opening of the chamber by back flow of fluid from the trap.

5. In a floor drain a bowl having a central discharge opening in the bottom, a tubular member extending vertically into the bowl and having an inlet opening in the side thereof providing a discharge chamber, a universally supported swing valve adapted to close the inlet by back flow into the chamher, a cap for the upper end of the tubular member and a perforate cover member for the bowl centrally supported by the cap.

In testimony whereof, I sign this specification.
